MIGRATION AND SUCCE8ISI0N OF HUMAN TYPES OF THE OLD STONE AGE OF 



EUROPE 



BY HENRY FAIRFIELD OSBORN 



Following President Osborn's paper and supplementing it was a dem- 

 onstration of models of ancient man, which was further illustrated with 

 lantern slides; 15 minutes. 



RESTORATIONS OF PITHECANTHROPUS AND PILTDOWN AND NEANDERTHAL 



MAN 



BY J. H. MC GREGOR 



The above two papers brought forth a discussion in which J. M. Clarke 

 and the two authors took part. 



There was next read from manuscript by the author and illustrated 

 with lantern slides and panoramic views a paper of general interest on 

 account of its bearing on Upper Cretaceous stratigraphy. 



EVIDENCE PROVING THAT THE BELLY RIVER BEDS OF ALBERTA ARE 

 EQUIVALENT TO THE JUDITH RIVER REDS OF DOG CREEK AND 

 COW ISLAND, MONTANA 



BY CHARLES H. STERNBERG 



iA1)stract) 



This paper will be illustrated with lantern .slides and several photographs, 

 including a panoramic view of Dog Creek, showing tlie three distinct horizons 

 of the Eagle sandstone, Clagett shales, and Judith River beds. The slides 

 show the Bear Paw shales on top of the Judith River beds at the head of an 

 eastern branch of Dog Creek called Taffy Creek. In the Bear Paw shales were 

 secured Fort Pierre Ammonites, Baculites, a new Clidastes, and bones of ple- 

 siosaurs. Immediately below, in the Judith River beds, we found a typical 

 locality for the vertebrates and made a large collection of Dinosaur, Myleda- 

 phus teeth, and vertebrae of Campsosaurus and the footed ischium of Lambe's 

 Stephanosaurus and other Belly River vertebrates. We found Myledaphus 

 teeth in the Eagle sandstones, leaves belonging to Belly River types, as well 

 as numerous shells from the .same horizon. We followed the strata down to 

 Cow Island and found the stratigraphy simple, but for the uplift of the strata, 

 everj^where. My work there substantiated Hatcher and Stanton in every par- 

 ticular, as noted in their bulletin of the U. S. Geological Survey. 



At 5 o'clock the Society adjourned for the day. In the evening the 

 members assembled to hear the address of the retiring President of the 

 Geological Society of America, and attended the iiomplimentary smoker 

 following this address.
